Valves and manual cct

Hey all,

I've got a 2012 r6. 2 things, and I'd appreciate the help

I want to check and adjust the valves. I've found only some info on how to do a valve adjustment/clearance. It seems like it'll take some time but its do-able. Anyone ever done this? Instructions and tips w pics too are greatly appreciated

I also wanna mention it has a manual cct installed, dont think that'll affect doing the valves but wanna check...

While I'm gonna do the valves I do wanna adjust if needed the cct installed. There's hardly any info on adjusting manual ccts already installed but all I hear is that it's not complicated to do, does anyone know how to adjust those too,
Which should be done 1st?

Check out the above video.

It'll probably be obvious when you answer, but what is "CCT" ?

Valves or valve shims ?

I myself are curious about obtaining a quality kit.

It appears he's specifying 1.5 to 2.4mm... which based on this...

may be the thickness and not diameter. That chart lists nothing for our model of Yami... but does mention some bit about hardness. <<"K&L shims exceed the maximum of the Apparent Rockwell Hardness “C” scale. Our shims “average” 47.0 compared to the 46.0 maximum. .................>>

So hardness, might be a factor, or maybe even "the" factor, in quality. I'd imagine that the manufacturers use more than one way to express that attribute, however.

Re: Valves and manual cct

You mean just shims. You don't replace valves unless they got F'd up. Some shops will exchange your old shims for a new shim if you only need a couple.

Re: Valves and manual cct

you can screw things up installing a manual CCT too tight. Whats wrong with the stock one??
Adjusting valves isnt hard... just need some good feeler gauges, a rectangle piece of cardboard, and a sharpie. And of course knowing your mm & thousandths of an inch math would help. Oh and dont forget your clearance ranges.

Yeah, that's what I mean. I'm sure my valves aren't fd up lolll...though my gas mileage is garbage and I hear and from reading the manual that means it may be time for a valve check, course may is the key word ha

Well my stock one went bad so the manual one was put in.. everyone says the stock ones fail easier

Ok... so it doesn't sound super hard. Just tedious I'm guessing...

I hear your supposed to tightened it hand tight, start it, see if the ticking goes away, then adjust more if it's not?
